Model 1 was adjusted for age. Model 2 was adjusted as for model 1 plus BMI and total energy intake. Model 3 was adjusted as for model 2 plus family history of diabetes, smoking status, physical activity, alcohol use, oral contraceptive use, and hormone replacement therapy. Model 4 was adjusted as for model 3 plus polyunsaturated:saturated fat ratio, glycemic load, and intakes of cereal fiber, trans fat, processed meat, carbonated soft drinks, fruit drinks, and coffee.
